What Makes a Carbide Spiral Tap Ideal for Hard Materials
2025-09-03
When machining hard materials like stainless steel, titanium, or superalloys, standard taps often fall short. The challenge isn’t just cutting precise threads—it’s doing so efficiently without excessive wear or breakage. This is where carbide spiral taps come into play. With superior hardness, heat resistance, and design efficiency, carbide spiral taps outperform conventional options in demanding applications. At NERES, we engineer these tools to deliver precision, durability, and performance.
How Carbide Spiral Taps Work
Carbide spiral taps are made from tungsten carbide, a material significantly harder and more heat-resistant than high-speed steel (HSS) or cobalt. This allows them to maintain sharp cutting edges even under high-temperature conditions. The spiral flute design efficiently evacuates chips, reducing heat buildup and preventing clogging.
NERES leverages advanced micro-grain carbide and proprietary coating technologies to enhance tool life and cutting performance. Our Spiral TAPS are designed for high-speed, high-precision applications in industries like aerospace, automotive, and medical manufacturing.

Spiral TAPS FAQ
What materials are best for carbide spiral taps
Carbide spiral taps excel in hard and abrasive materials such as stainless steel, Inconel, titanium, and hardened steels. They are also ideal for high-temperature alloys where standard taps would fail quickly.
How does the spiral flute improve performance
The spiral flute design allows continuous chip evacuation, reducing heat accumulation and preventing chip welding. This results in longer tool life, better thread quality, and fewer breakages during deep-hole or blind-hole threading.
Can carbide spiral taps be used on CNC machines
Absolutely. NERES carbide spiral taps are designed for compatibility with CNC machining centers and lathes. Their robust construction and high precision make them suitable for high-speed, automated operations.
